Humans are still evolving

A new study published in Massachusetts (USA) shows evidence of human evolution is continuing.

A group of scientists led by Stephan Stearns, an expert in evolutionary biology at Yale University, argued that the natural selection process in modern humans is not for survival reasons, but rather for differences. about women's fertility.

Accordingly, women with more children are more likely to pass on their traits to the next generation. Time said Stearns' team tracked statistics from 2,238 postmenopausal women at the Framingham Heart Research Institute, a medical history of 14,000 people in Framingham, Massachusetts since 1948. Researchers looked for links between physical traits in women, including height, weight, blood pressure and cholesterol levels with their number of births.

Accordingly, full (but not obese) women tend to have more children. If these trends continue without any profound changes in the town being modeled for research, in the next 10 generations, ie in 2049, an average Framingham woman will be 2cm lower and heavier. 1kg compared to the present, healthier, have first-born children five months earlier and enter menopause 10 months later than now, ie natural evolution will continue.
